CHAIR.

SPECIFICATION forming part of Letters Patent No. 523,839, dated July 31,1894.

Application led May 8, 1893- Serial No. 473,495. (No model.) i

To alla/hom t may concern,.-

Beit known that I, LEROY C. LAZEAR, a citizen of the United States,residing at Chicago, Cook county, Illinois, have invented a new anduseful Improvement in Chairs, of which the following is a speciiication.

My invention relates to chairs, and has for its object to provide animproved convenient and easily operated chair, and particularly onewhich shall be capable of serving as a rocking chair, and rotatingchair.

It is illustrated in the accompanying drawings, wherein f Figure 1 is across section of the chair body at one side of the center. Fig. 2 is alike cross section near the center. Fig. 3 is a plan view of the rockerplatform; Fig. 4,a plan view of the platform of rotation. Fig. 5 is across section of modification. Fig. 6 is a detail of the 'leg supportingpiece. t

Like parts are indicated by the same letters in all the figures.

A is the seat, B the back, C the frame portion of the chair.

D, D are the rockers removably secured within the lower portion of theframe, for eX- ample, by means of screws as shown and connected with thecross pieces D D for strengthening. Each rocker has the upwardlyprojecting part'D2 with the laterally projecting plate D3 thereon. Theserockers rest upon the rocker platform E, which has the projectingportions E', E and E2, E2, to serve as bearings for the rockers. Theplate is centrally enlarged, and provided with the downwardlyprojecting\central pivot cylinder E3, which passes into the leg socketor support F, and has at its lower end,-the screw head G, which holds itin position. The leg socket F is provided with the laterally projectingrib F F in pairs, between which are secured the legs F2, F2, provided,for example, with outer casters F3. On the upper portion of these legsand the support or socket is rigidly placed the platform H, upon whichthe rollers J, J are adapted to bear. The rollers J are journaled on theouter extremities of the arms J 2, which arms are secured to the collarJ a rigid on and rotating with the pivot cylinder E3. In the case ofthe` rollers J they are provided with sockets in the lower portion ofthe plat-l form E, as indicated in Fig. 5.

K is a stirrup or downwardly and outwardly projecting part on each sideof the platform E, and K', K are spiral springs interposed be- 'by theaction of the spiral spring projecting legs F2 F2 tion by the elasticannulus R.

The use and operation of my invention are as follows: My chair in itscomplete form as illustrated in the drawings is what I have described asan elevated, rotating rocking chair, since it presents in one` device anelevated rocking chair, and one which is also capable of rotation. Thechair can be used as a rcker, the rockers resting upon the platform E,and the chair is returned to its normal position K. If the person usingthe chair desires to turn it about so as to face in any direction, hehas onlv to swing the chairin the usual manner of a rotating chair,whereupon it will travel about the center of the pivot cylinder E3. Therocker platform being supported by means of the rollers upon the roller`or, lower platform, the chair can be easily moved about on the rollersF3.

I claimt The combination in a chair, of a chair frame C, rockers D Dremovably secured thereto,

their ends inside the frame and provided with flat bearing surfaces, acentral rocker platform E provided with projecting flat surfaces E', E2,upon which said rockers bear, and a downwardly projecting cylinder E3integral with said platform, a lower platform H having a centraldownwardly projecting socket F integral therewith adapted to receive thecylinder of the rocker platform, and laterally secured thereto,antifriction rollers J J intermediate between said rocker-and lowerplatforms and detached from -both platforms, horizontally projectingplates D3 and K rigid respectively with said rockers and rockerplatform, and springs K intermediate between said projecting plates, theplatforms, rockers and associated parts being beneath and protectedv by,the chair frame, all substantially as described and for the purposespecified.
